INA angular contact ball bearing assembly quality decided to the cause of the damage

Complete sets of INA bearing outer ring radial runout Kea outer ring in different angular position, facing the outside appearance and inner ring fixed between the difference between the maximum and minimum radial interval. In the above points on both sides of the angular position or in the neighbourhood of the rolling bearings imported bearing body shall, within their way or inner ring opposite guard ( Tapered roller bearing) In contact faces the angular contact ball bearing parts in the normal position. Complete set of bearing inner ring end face a race to beat the Sia inner ring in different angular position, from the inner circle axis radial interval is equal to the diameter of inner ring raceway contact of half, inner ring reference face and related to the maximum and minimum axial spacing between a fixed point. Inner and outer raceway shall with all contact roller. Complete sets of INA bearing outer ring end face a race to beat Sea outer ring in different angular position, from the outer axis radial interval is equal to the diameter of outer ring raceway contact of half, outer ring reference face and the correlation between the inner ring of a fixed point as the difference between maximum and minimum axial interval. Inner and outer raceway shall with all contact roller. Use brute force, when installation directly with a hammer percussion bearing to bearing damage; Is the main cause of deformation. Installation does not reach the designated position, install a deviation or failure to bearings, angular contact ball bearing clearance is too small. Inside and outside the circle is not in the same center of rotation, resulting in different heart. Suggestion: select the appropriate or professional bearing installation tools, installed with a special instrument to detect. According to the survey, poor lubrication is one of the leading causes of premature failure of the bearing. Main reasons including: failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication method is not correct, and so on. Suggestion: to select the correct lubricant or lubricating oil, use the correct lubrication filling way. Pollution can also cause premature bearing damage, pollution is refers to the dust, metal scraps into INA bearings inside. Main causes include: early to open the bearing packing before use, cause pollution; When installation work environment is not clean, cause pollution; Bearing of the working environment is not clean, working medium pollution, etc. Suggestion: before use it is best not to unpack the bearing; Keep the installation environment clean, when installation to use the bearing in cleaning; Enhance the angular contact ball bearing sealing device. Fatigue damage is a common way of damaged bearing. Common fatigue failure reasons might be: bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment aging, etc. Complete INA bearing inner ring of the radial runout Kia inner ring in different angular position, the inner hole between the relative outer appearance and a fixed point of the difference between the maximum and minimum radial interval. In the above points on both sides of the angular position or in the neighbourhood of the rolling element and the inner and outer ring raceway or inner ring opposite guard ( Angular contact ball bearing) Faces in contact with the bearing parts in the normal position.
